Share 'Where should I put the Open Social code in NING?'

Hi,   I'm new here from creators. I know my javascript but new to open social. I'm testing this. http://developer.ning.com/docs/opensocial/1.0/overview/profile-data.html  I don't know where to put these javascript code in NING? Or should I include the xml tags? I tried page and text box in the main page. It doesn't work.   Thank you.
